Kurita Begins Full-Scale Sales of a Standard-Type Wastewater Treatment System
- Enabling a 40% Reduction in the Cost of Introduction through the Adoption of Innovative Tower Tanks and Thorough Standardization -

Kurita Water Industries Ltd. (Head Office: Nakano-ku, Tokyo; President: Toshiyuki Nakai) is pleased to announce that it has begun full-scale sales of a standard-type wastewater treatment system as part of its water treatment facilities business. It is an innovative wastewater treatment system which features the use of FRP tower tanks that are 10 meters tall. It permits a 40% cost reduction in their introduction, compared to previous wastewater treatment systems from Kurita.

The first standard-type wastewater treatment system

To reduce the cost of introduction of its wastewater treatment systems, Kurita has been striving to improve the efficiency of treatment technologies and systems for treatment (software). However, except for some products, our tanks (hardware), which are the main components of the wastewater treatment systems, were custom-made concrete tanks which required on-site construction work. This made it difficult to reduce the cost of introduction of the systems.

The standard-type wastewater treatment system features unified specifications and drawings of its components, including the tower tanks. Its units, including pipes and wires, are assembled at the manufacturing plant before the system is delivered to the customer’s plant. This makes the on-site construction work extremely simple, involving only the allocating of individual units, connecting piping, and electrical wiring work. As a result, the period between the commencement of construction work and completion of test operation, which used to be about six months, has been shortened to around three months. At the same time, the cost for introducing the new wastewater treatment system is 40% less than the previous systems from Kurita.

The new wastewater treatment system is also an outstanding space-saving system. It uses tower tanks to take advantage of their height while chemical feeding equipment, pumps, and other components come in compact units. This has resulted in a 20% smaller installation area compared to previous systems from Kurita.

Kurita delivered the first standard-type wastewater treatment system to Nissey Delica Corporation in July this year, and the system has been operating stably. Kurita will promote this product as new equipment or equipment to enhance the capacity of existing equipment in a wide variety of industries including food, beverage, pharmaceutical, and electronic industries. It will thus respond to customers’ requests such as reduced introduction costs, reduced maintenance and management costs, a more effective utilization of the plant site area, and prompt response to effluent regulations, not to mention the stable operation of wastewater treatment facilities, with an aim to increasing its share of the product in the market of water treatment systems.

Features of the standard-type wastewater treatment system

A 40% smaller cost of introduction
The system uses tower tanks instead of conventional concrete tanks. This simplifies the onsite construction work significantly. As a result, the cost of introduction of the system is 40% less than previous systems from Kurita.

A 20% smaller installation space
The system uses tower tanks which are 10 meters tall and come with compact incidental equipment. This has resulted in a 20% smaller installation space compared to previous systems from Kurita.

A 50% shorter period of onsite construction work
The standardized pieces of equipment permit a 50% shorter period of onsite construction work. The period between the commencement of construction work and completion of test operations, which is generally about six months, has been halved to around three months.

Compatibility with both aerobic treatment and anaerobic treatment
Biological treatment processes of wastewater are largely divided into aerobic treatment and anaerobic treatment. This system is compatible with both of them. Kurita will propose the optimal system for each customer based on the amount of water to be treated, the quality of the raw water, and the quality of discharged water.

Compatibility with Kurita's maintenance service for water treatment facilities
The system is also compatible with Kurita's new maintenance service for water treatment facilities. The service visualizes the operating status of each wastewater treatment system and raw water quality, thereby contributing to stabilizing wastewater treatment and reducing the labor for operation management.
